IMPROVEMENT IN SHUTTER-FASTENINGS.

Specification forming part of Letters Patent No. 146,028, dated December30, 1873; application filed November 1, 1873.

To all whom it may concern:

Be it known that I, HENRY A. SKINNER, of the city and county ofWorcester, in the State of Massachusetts, have invented a new andImproved Blind-Fastener, of which the following is a specification:

In the accompanying drawings, like letters indicate like parts.

Figure 1 is a top view of my invention. Fig. 2 is an end view of thesame. Fig. 3 is a longitudinal section.

My invention is designed for use upon window blinds or shutters. Bygiving to my fastenter a rotary movement, I am able to actuate it by theweight or mass of metal projecting upon one side of it, and serving as ahandle, which, in falling, brings the catch to a horizontal position,inclosing the staple or post upon the window-sill.

A spindle or rod, A, is made with catches B and 0, both lying on oneside of it, and a handl-e, D, upon the other side, opposite to the catchB. These are all cast in one piece, in the shape shown in the drawing.The catches B and 0 have a beveled face, and the rod A turns within abarrel, E, which, being furnished with a screw-thread, is secured intoand through the blind, projecting upon both sides. Projecting lips F Fterminate it on both ends, and these, too, are beveled, and are incontact with the catches B and C, respectively. The barrel E is cast intwo longitudinal sections, and are fastened together at a by a smallscrew and rivet. An opening or hole, I), is made, through which watermay escape that, in rainy weather, may have worked its way within thecase or barrel E, and which otherwise, especially in cold weather, mightoccasion injury. A shoulder, c, is cut into the upper part of this case,to prevent the rod A from turning too far. In closing the blind thebeveled face of the catch B strikes against the post G, and is tippeddownward, allowing the post to be admitted between it and the lip F,until, having passed beyond it, the weight of the handle D, which hasbeen elevated by this operation, brings the catch B back to itshorizontal position, inclosing the post G, and the blind is secured inplace.

On opening the blind the handle D is raised, and the catch clears thepost as the whole is swung outwardly, and when fully open the catch Cengages in a similar manner with its corresponding staple in the outerwall of the house. Instead of using the case or barrel E, the rod andconnected catches may be secured under the blind by staples or othermeans.

The rotating movement or the substitution of a falling weight in theplace of a spring may obviously be secured by placing the working partsin a different position relatively to the blind 5 but such contrivances,notwithstanding some modifications of shape, would obviously be withinmy invention.

I claim as a novel and useful invention, and desire to secure by LettersPatent- 1. The rotating blind-fastener A B G D, with or without its caseE, substantially as described.

2. The blind-fastener consisting of the rotating rod or spindle A, withits catches B O, handle D, and case or barrel E, with its lips F F, madeand used as and for the purpose specified.
